[0002] Polyester is a polyester fiber, a synthetic fiber obtained by spinning a polyester formed by polycondensation of organic dibasic acids and dibasic alcohols, belonging to high molecular compounds. Polyester has high strength, high modulus, and low water absorption, and has a wide range of uses as civil fabrics and industrial fabrics. During the production of polyester filaments, high-temperature waste gas with complex components is generated in the processes of melt spinning, heat setting, and oil agent volatilization.

[0003] A Chinese invention patent with the authorization announcement number CN217549308U, an exhaust gas purification and treatment device for carbon molecular sieve production. The dust collection box one and dust collection box two provided in this device can recycle dust for secondary utilization. The anti-slip pads provided can prevent losses caused by accidental loosening during work. At the same time, the anti-slip pads can easily remove the dust collection box when needed. The grooves provided in the first filter layer can facilitate the falling of dust during vibration. The pneumatic telescopic rod and spring provided can make the first filter layer vibrate to let the dust fall. However, the waste gas generated in polyester filament production contains harmful pungent gases, and these gases are the sources that cause serious harm to the environment.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 8 , an exhaust gas purification and treatment device for polyester filament production, including a purification chamber 1. A motor base 3 is fixedly connected to the upper surface of the purification chamber 1. A driving motor 2 is fixedly connected to the upper surface of the motor base 3. The output end of the driving motor 2 is fixedly connected to a first circular plate 4. An atomization component 5 for purifying and treating exhaust gas is arranged at the bottom inside the purification chamber 1.

[0024] Such as Figures 3 - 4As shown in the figure, the atomization assembly 5 includes a liquid storage tank 51 fixed to the inner bottom of the purification chamber 1, a water pump 52 fixed to the front and rear sides of the purification chamber 1, and a bucket-shaped frame 58 fixed to the middle of the inner surface of the purification chamber 1. Both the output end and the input end of the water pump 52 are fixedly connected with a water pipe 54. One end of a water pipe 54 extends into the interior of the liquid storage tank 51, and one end of the other water pipe 54 extends into the interior of the purification chamber 1 and is fixedly connected with a telescopic hose 53. One end of each of the two telescopic hoses 53 is fixedly connected with a rectangular atomization pipe 55, and a swing assembly 56 is arranged on the lower surface of the rectangular atomization pipe 55.

[0025] The bucket-shaped frame 58 is located above the liquid storage tank 51. Grooves are formed on both sides of the inner surface of the purification chamber 1. Connecting plates are fixedly connected to both sides of the outer surface of the rectangular atomization pipe 55, and one side of the connecting plate extends into the groove and slides mutually. A chamber cover 7 is sleeved on the upper surface of the purification chamber 1. An activated carbon plate 9 is fixedly connected to the upper surface of the chamber cover 7, and an air outlet pipe 8 is fixedly connected to the inner surface of the activated carbon plate 9.

[0026] When waste gas enters the interior of the purification chamber 1, two water pumps 52 are started. The two water pumps 52 transport the medicament inside the liquid storage tank 51 to the interior of the rectangular atomization pipe 55 through the water pipes 54, and then spray it in the form of atomization through the rectangular atomization pipe 55. At this time, the atomized medicament contacts the waste gas inside the purification chamber 1 to remove harmful substances in the waste gas, so that the waste gas can be effectively treated. The treated waste gas is purified and deodorized through the air outlet pipe 8 and then discharged. The atomized medicament solution falls on the surface of the bucket-shaped frame 58 and converges into small water flows, and the water flows then flow into the interior of the liquid storage tank 51 for recycling.

[0027] As Figures 4 - 5 shown in the figure, the swing assembly 56 includes a swing plate 563 fixed to the lower surface of the rectangular atomization pipe 55 and a transmission shaft 565 rotatably arranged on the inner bottom of the liquid storage tank 51. A second circular plate 561 is fixedly connected to the top of the transmission shaft 565, a driving rod 562 is fixedly connected to the edge of the upper surface of the second circular plate 561, and a through groove 564 is formed inside the swing plate 563.

[0028] The top of the transmission shaft 565 penetrates through the interior of the bucket-shaped frame 58. The second circular plate 561 is located below the swing plate 563. The top of the driving rod 562 penetrates through the through groove 564 and is fixedly connected to the lower surface of the first circular plate 4.

[0029] When the rectangular atomizing tube 55 sprays the atomized medicament, since the rectangular atomizing tube 55 is in a fixed position and the spraying range is limited, part of the waste gas cannot come into contact with the medicament spray and is directly discharged, resulting in low efficiency of waste gas purification treatment. Before treating the waste gas, the driving motor 2 is turned on to drive the first circular plate 4 to rotate. The first circular plate 4 drives the driving rod 562 to perform a circular motion. The driving rod 562 drives the swing plate 563 to swing back and forth inside the purification chamber 1. At the same time, the driving rod 562 slides back and forth left and right in the through groove 564. The swing plate 563 drives the rectangular atomizing tube 55 to swing back and forth inside the purification chamber 1, thereby effectively increasing the spraying range of the rectangular atomizing tube 55, effectively improving the effect of waste gas purification, and significantly reducing the amount of waste gas discharged to the outside world.

[0030] As Figures 4 - 5 shown, turbulence components 57 are arranged at the middle positions on both sides of the inner surface of the purification chamber 1. The turbulence components 57 include a rotating shaft 571 rotatably connected to the middle positions on both sides of the inner surface of the purification chamber 1 and racks 573 fixed to both sides of the lower surface of the swing plate 563. A gear 572 is fixedly connected to the middle of the outer surface of the rotating shaft 571, and three stirring fan blades 574 are evenly and fixedly connected to the outer surface of the gear 572.

[0031] The racks 573 are fixedly connected to the lower surface of the swing plate 563 through connecting rods. The racks 573 are meshed with the gear 572, and the stirring fan blades 574 are located above the hopper-shaped frame 58.

[0032] Driven by the swing plate 563, the rectangular atomizing tube 55 can swing back and forth inside the purification chamber 1, effectively expanding the spraying range of the rectangular atomizing tube 55, and can purify the harmful substances in the waste gas to a great extent. However, the waste gas flows rapidly in the same direction, resulting in a short contact time between the air flow and the spray, and the gas at the center of the air flow cannot come into contact with the spray. Therefore, when the swing plate 563 moves in a reciprocating cycle, the swing plate 563 synchronously drives the racks 573 to move back and forth. The racks 573 will drive the gear 572 to rotate forward and backward, and drive the stirring fan blades 574 to rotate back and forth through the rotating shaft 571, which can stir the air flow flowing out from inside the hopper-shaped frame 58. The rapidly flowing air flow contacts and impacts the stirring fan blades 574, so that the air flow forms a turbulent flow with irregular flow under the stirring of the stirring fan blades 574, making the air flow stay in the purification chamber 1 for a longer time. The stirring fan blades 574 can fully stir and contact the water mist of the spray of the rectangular atomizing tube 55 and the air flow, further improving the effect of the atomized medicament solution on waste gas purification treatment.

[0033] As Figure 6As shown in the figure, pretreatment components 6 are arranged on both sides of the inner surface of the purification chamber 1 near the bottom. The pretreatment components 6 include an air inlet pipe 61 fixed to both sides of the inner surface of the purification chamber 1 near the bottom and a stirring blade 62 fixed to the bottom of the outer surface of the transmission shaft 565. One side of the air inlet pipe 61 is fixedly connected with a circular frame 63, and an air outlet 64 is arranged inside the circular frame 63.

[0034] One side of the air inlet pipe 61 extends out of the inside of the purification chamber 1. The air inlet pipe 61 is Z-shaped and is located inside the liquid storage tank 51. The stirring blade 62 is inside the liquid storage tank 51 and is located above the circular frame 63.

[0035] Before the waste gas enters the inside of the purification chamber 1, the waste gas contains a large amount of impurities such as fluff and dust, and it is necessary to remove the impurities in the waste gas. When the waste gas enters the inside of the liquid storage tank 51 through the air inlet pipe 61, the waste gas is ejected through the air outlet 64, forming small bubbles in the reagent solution inside the liquid storage tank 51, so that the impurities in the waste gas are dust-settled by the solution inside the liquid storage tank 51. At the same time, the solution can carry out preliminary purification treatment on the harmful gases in the waste gas, reducing the difficulty of the subsequent spray treatment of the rectangular atomizing pipe 55. And the stirring blade 62 will rotate with the transmission shaft 565 to stir the solution inside the liquid storage tank 51, which can break the bubbles into smaller bubbles, improve the effect of solution dust-settling and purification, and can also prevent the solution around the air outlet 64 from contacting the waste gas for a long time, resulting in a low reagent concentration, and improve the uniformity of the reagent in the solution inside the liquid storage tank 51.

[0036] As Figures 7 - 8 shown in the figure, a feeding component 65 is arranged on the front side of the inner surface of the purification chamber 1. The feeding component 65 includes a reagent box 651 fixed to the front side of the inner surface of the purification chamber 1, a worm gear groove 652 arranged on the outer surface of the transmission shaft 565, and a worm 654 rotatably connected to the front side of the inner surface of the liquid storage tank 51. One side of the worm 654 is fixedly connected with a first worm gear 653. The lower surface of the reagent box 651 is fixedly connected with a fixed cylinder 655. The outer surface of the fixed cylinder 655 is rotatably connected with a rotating cylinder 656. The outer surface of the rotating cylinder 656 is fixedly connected with a second worm gear 657. Liquid outlet holes 658 are arranged at the bottoms of the rotating cylinder 656 and the fixed cylinder 655.

[0037] The first worm gear 653 meshes with the worm gear groove 652, the worm 654 meshes with the second worm gear 657. A feeding pipe is arranged on one side of the reagent box 651, and one end of the feeding pipe extends out of the inside of the purification chamber 1.

[0038] During the waste gas treatment process, the concentration of the medicament inside the liquid storage tank 51 will continuously decrease. To ensure the effect of waste gas purification, it is necessary to keep the concentration of the medicament within a certain range. When the transmission shaft 565 rotates, it drives the worm gear groove 652 to rotate, and synchronously drives the worm 654 to rotate through the first worm gear 653. The worm 654 drives the rotating cylinder 656 to rotate on the outer surface of the fixed cylinder 655 through the second worm gear 657. At this time, the liquid outlet 658 on the rotating cylinder 656 coincides with the liquid outlet 658 on the fixed cylinder 655. At this time, the medicament inside the medicament box 651 drips into the inside of the liquid storage tank 51 through the liquid outlet 658, so that the concentration of the medicament in the solution inside the liquid storage tank 51 is always maintained at a certain concentration, ensuring the effect of waste gas treatment.

[0039] Usage method: Before the waste gas enters the inside of the purification chamber 1, the waste gas contains a large amount of impurities such as lint and dust, and it is necessary to remove the impurities in the waste gas. When the waste gas enters the inside of the liquid storage tank 51 through the intake pipe 61, the waste gas is ejected through the air outlet 64, forming small bubbles in the medicament solution inside the liquid storage tank 51, so that the impurities in the waste gas are dust-settled by the solution inside the liquid storage tank 51. At the same time, the solution can preliminarily purify the harmful gases in the waste gas, reducing the difficulty of the subsequent spray treatment of the rectangular atomizing pipe 55. And the stirring blade 62 will rotate with the transmission shaft 565 to stir the solution inside the liquid storage tank 51, and the bubbles can be broken into smaller bubbles, improving the effect of dust-settling and purification of the solution. When the transmission shaft 565 rotates, it drives the worm gear groove 652 to rotate, and synchronously drives the worm 654 to rotate through the first worm gear 653. The worm 654 drives the rotating cylinder 656 to rotate on the outer surface of the fixed cylinder 655 through the second worm gear 657. At this time, the liquid outlet 658 on the rotating cylinder 656 coincides with the liquid outlet 658 on the fixed cylinder 655. At this time, the medicament inside the medicament box 651 drips into the inside of the liquid storage tank 51 through the liquid outlet 658, so that the concentration of the medicament in the solution inside the liquid storage tank 51 is always maintained at a certain concentration; Start two water pumps 52. The two water pumps 52 convey the medicament inside the liquid storage tank 51 to the inside of the rectangular atomizing pipe 55 through the water pipe 54, and then spray it in the form of atomization through the rectangular atomizing pipe 55. At this time, the atomized medicament contacts the waste gas inside the purification chamber 1 to remove harmful substances in the waste gas. Before treating the waste gas, turn on the drive motor 2 to drive the first circular plate 4 to rotate. The first circular plate 4 drives the drive rod 562 to perform a circular motion. The drive rod 562 drives the swing plate 563 to swing back and forth inside the purification chamber 1. At the same time, the drive rod 562 slides left and right in a reciprocating manner inside the through groove 564. The swing plate 563 drives the rectangular atomizing pipe 55 to swing back and forth inside the purification chamber 1, thereby effectively increasing the spraying range of the rectangular atomizing pipe 55. The swing plate 563 synchronously drives the rack 573 to move back and forth. The rack 573 drives the gear 572 to rotate forward and backward, and drives the stirring fan blade 574 to rotate back and forth through the rotating shaft 571, which can stir the airflow flowing out of the funnel-shaped frame 58. The rapidly flowing airflow contacts and impacts the stirring fan blade 574, so that the airflow forms a turbulent flow with irregular flow under the stirring of the stirring fan blade 574, making the residence time of the airflow inside the purification chamber 1 longer. The stirring fan blade 574 can make the water mist sprayed by the rectangular atomizing pipe 55 fully contact the airflow.

[0040] As described above, it is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
